Dr. Rosenblum returned to MPI, where he had been a Senior Policy Analyst, after working as a specialist in immigration policy at the Congressional Research Service. He was a Council on Foreign Relations Fellow detailed to the office of U.S. Sen. Edward Kennedy during the 2006 Senate immigration debate and was involved in crafting the Senate's immigration legislation in 2006 and 2007. He also served as a member of President-elect Obama's Immigration Policy Transition Team in 2009.

He has published more than 60 academic journal articles, book chapters, and policy briefs on immigration, immigration policy, and U.S.-Latin American relations. He is the coeditor (with Daniel Tichenor) of The Oxford Handbook of International Migration (Oxford University Press).

Dr. Rosenblum earned his B.A. from Columbia University and his Ph.D. from the University of California, San Diego, and is an Associate Professor of Political Science at the University of New Orleans.

MPI researchers, along with analysts from the Government Accountability Office and American Immigration Council, discuss the findings from an MPI report that examines the 3.7 million deportations that have occurred in the United States since establishment of the Department of Homeland Security in 2003, as well as lessons that can be learned for future policy and possible administrative action.

Estimates of unauthorized immigrant populations that could receive relief from deportation under potential executive action scenarios to expand the Deferred Action for Childhood Arrivals (DACA) program, extend deferred action to other populations, or refine immigration enforcement priorities are discussed during this webinar.

The flow of unaccompanied children from Central America and Mexico to the United States has surged 90 percent since last year, with government officials predicting that it might reach 90,000 by the end of the fiscal year in September—and perhaps 130,000 next year. This telebriefing discusses factors behind the flows as well as short- and longer-term policy options for improving how the U.S. immigration system interacts with this population with distinct needs.

This MPI panel discussion examines the U.S. deportation system with analysis on migrant apprehensions, removals, returns, and criminal prosecutions, and launches the report, "The Deportation Dilemma: Reconciling Tough and Humane Enforcement."

New migration patterns at the U.S. Southwest border, including a shift in border crossers from primarily Mexican men to Central American families, and from the California and Arizona borders to the Rio Grande Valley, have important implications for U.S. border policy and enforcement strategies, raising questions of what consequences might deter unauthorized Central Americans while still meeting international obligations to protect vulnerable migrants.
